Abstract:

The rocket-borne version of the mass spectrometer to be used for helium measurement was designed, fabricated, assembled, and is being tested. The system that will be used to calibrate mass spectrometers for atomic oxygen and nitrogen was completed. Testing of the system components and operation is being co ducted. The time-of-flight mass spectrometer remained at the Bendix Research Laboratories, but a new pumping system for the instrument was installed on a test console. The ceramic ring design cold cathode ionization gauge was completed and calibrated. The vacuum gauge calibration system was in operation. Pressure readings of the McLeod gauge pressure standards were compared, and the difference in their readings was traced to a systematic error in determining the final pressure of the compressed gas in the closed end capillary.
